TCM809 - TelCom Semiconductor

TCM809 3-PIN UP RESET MONITORS

The TCM809 and TCM810 are cost-effective system supervisor circuits designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. No external components are required. The reset output is driven active within 20msec of V CC falling through the reset voltage threshold. Reset is maintained active for a minimum of 14.
